FIELD OF THE INVENTION

This invention is in the field of devices used to hold a drinking glassor cup without spilling, by attachment to any available structure, suchas a chair or an automobile dashboard.

BACKGROUND

Many human activities are conducted in environments where the presenceof a table for refreshment purposes is not feasible. Probably foremostamong these environments is the automobile, where an average personoften spends appreciable amounts of time. Other such environments areworkshops and crowded computer work stations. Because a person oftenspends considerable time in these places, he usually wants to consumeliquid refreshment while he is occupied with his driving or working. Theaverage automobile has little or no flat space in which to set abeverage container such as a glass, can or cup. Similarly, even though aworkbench or a computer work station may have flat surfaces, they areusually crowded, and spilled beverages can create a major problem.

It is desirable, then, to have a device which could hold a beveragecontainer in an environment such as these. Many devices have beencontrived to serve this need. Most often, they incorporate a gimbaledmount of some kind with a holder suspended from a single point.Sometimes these devices can mount directly to an environmental surface,and sometimes they require that a permanent mounting fixture be mountedon the surface prior to hanging the drink holder from the fixture. Thislatter method has the obvious disadvantage that the beverage holdercannot be moved from one place to another without first installing a newmounting fixture.

The devices which can be mounted directly to an environmental surfaceare usually somewhat limited to surfaces having a given orientation.This is because they can only be adjusted about one, two or three axesof rotation. Depending upon the surface to which the drink holder isattached, this limited scheme of adjustment may leave the drink holdertoo high or low, tilted at an angle or out of position horizontally.When the available surfaces are severely limited, such as in anautomobile, the inability to properly adjust the drink holder may makeit useless.

Another disadvantage suffered by most known drink holders is that theyare awkward and relatively bulky, consuming valuable space even when notin use. It would be helpful to be able to fold up a drink holder into aminimum amount of space when it is not in use. This can also be helpfulin packaging the device for sale.

SUMMARY OF THE INVENTION

This invention is a stable drink holder which can be adjusted about fouraxes of rotation to facilitate mounting of the holder on almost anysurface while making possible the positioning of the beverage containerin a useful orientation. This drink holder also will fold up into asmall package for storage, consuming the minimum amount of spacenecessary. The holder is also adjustable to different heights ofbeverage containers, and it can be used with large mugs as well asbeverage cans or glasses.

The holder attaches to an available surface by means of a large springclamp which can have suction cups. Extending from this attachment deviceis a linkage of longitudinal elements having four axes of rotationaladjustment, with the longitudinal elements being connected end-to-end.The axes of rotation are located at the end-points of the longitudinalelements. They can be bolts and wing nuts or ball-detent mechanisms, ora combination of both.

Connected to the linkage on the end opposite the clamp is a frame towhich are attached pivotable base and a pivotable hoop. The base andhoop are pivoted perpendicular to the frame, so that a container can beset upon the base and encircled by the hoop. When not in use, the baseand hoop can be pivoted parallel to the frame, and the linkage can befolded frame.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

As seen in FIG. 1, the adjustable drink holder A is clamped to avertical surface B for support. The surface to which it is clamped neednot be vertical or even flat. It can be at virtually any angle, and itcan have any shape as long as it is small enough to fit in the clamp300.

As shown in FIG. 2 and 3, frame 100 has a bulkhead 110 generally heldvertical when the holder is in use. Connected along the edges ofbulkhead 110 are sidewalls 120, also vertical, in which are formedchannels 122 and channel cutouts 123, which are approximately twice aswide as channels 122.

Attached to sidewalls 120 is hoop 130, by means of hoop pivot pins 132.Pivot pins 132 are semicircular in cross section with a major diameterapproximately equal to the width of channel cutouts 123, and with aminor diameter approximately equal to the width of channel 122.

Spaced along bulkhead 110 are horizontal grooves 112 into which an edgeof hoop 130 can insert when hoop 130 is pivoted to its horizontalposition. Grooves 112 could easily be replaced by properly placed ridgesor friction bumps (not shown).

Base 140 is a rectangular platform pivotably attached to the lower endsof sidewalls 120. Base 140 has raised rim 142 around three sides, and itis pivoted along its forth side. Base 140 also has a series ofconcentric raised ridges 144 on its upper surface to facilitate thecollection of liquid, such as condensate running off a cold can. Cutthrough ridges 144 is a draining groove 145 leading to a drain hole 146.

Pivot linkage 200 is attached to bulkhead 110 on the side opposite fromhoop 130 and base 140. Linkage 200 consists of four pivot points 210,220, 230, 240 at the connections between three link elements 215, 225and 235, including both free ends. Pivot points 210, 220 and 230 areshown as bolts having wing nuts, and pivot point 240 is shown as aball-detent mechanism. This mechanism has a series of spring loadedballs seated in shallow detents (not shown) to hold a desired angularposition. Either type could be used at any pivot point. Pivot point 210is mounted directly on bulkhead 110, while pivot point 240 is mounteddirectly on spring clamp 300. Spring clamp 300 is well known in the art,having handles 310 which can be squeezed together against the pressureof spring 320 to cause jaws 330 to open.

Pivot point 210 has an axis of rotation that is parallel to the verticalaxis of the bulkhead 110. Pivot point 240 has an axis of rotation thatwill remain coplanar with the axis of pivot 210. These two axes could beparallel or they could intersect at any angle. This means that thevertical axis of the frame 100 can be aligned vertical relative to theground regardless of the angle of inclination of the surface to whichthe apparatus is attached.

Pivot points 220 and 230 have axes of rotation that are always parallelto each other, and they define a plane that is always perpendicular tothe plane defined by the axes of pivot points 210 and 240. This meansthat rotation of pivot points 220 and 230 results in translational,rather than purely angular movement of frame 100. Link element 225 canhave various lengths according to the magnitude of translationalmovement that is required. This facilitates the raising of frame 100high above a low attachment surface or suspending frame 100 well below ahigh attachment surface. It also facilitates the location of frame 100either close to or well away from the attachment surface, as desired.

Of course, pivot point 210 is manipulated to cause frame 100 and base140 to face the desired direction. Pivot point 240 is manipulated asrequired to bring frame 100 to vertical, regardless of the angle atwhich clamp 300 is attached to the available surface.

In order to use the adjustable drink holder, a suitable clamping surfaceis first selected. The only requirements are that the surface fit withinthe clamp and provide sufficient support for the device and beveragecontainer. Clamp 300 is clamped securely onto the selected surface.Then, pivot point 240 is rotated until the axis of pivot point 230 ishorizontal. This ensures that the base 140 can be horizontal after alladjustments are made. The ball-detent mechanism of pivot point 240 willhold its position without any tightening.

Wing nut 232 on bolt 234 is then loosened, and pivot point 230 isadjusted to achieve the desired height and distance of the frame 100from clamp 300. Wing nut 232 is then tightened. Next, wing nut 222 onbolt 224 is loosened, and pivot point 220 is adjusted to bring base 140to horizontal. Wing nut 222 is then tightened. Finally, wing nut 212 onbolt 214 is loosened, and pivot point 210 is adjusted to cause frame 100and base 140 to face the proper direction. Then, wing nut 212 istightened. Loosening and tightening of wing nuts may not be necessary,depending upon the materials of construction and the weight of thebeverage container.

After this adjustment, the height of hoop 130 is set as desired to matchthe beverage container by pivoting hoop 130 until it is parallel tobulkhead 110 and then sliding hoop 130 up or down in channels 120. Whenthe desired height of hoop 130 is reached, it is pivoted down until itis perpendicular to bulkhead 110, locking hoop 130 in place in desiredgroove 112. Base 140 is pivoted perpendicular to bulkhead 110.

FIG. 4 shows hoop 130 in place for use with a beverage can, while FIG. 5shows hoop 130 stored against bulkhead 110 for use with a large mug.

When the drink holder is not in use, it can be left clamped in place.Hoop 130 is pivoted parallel to bulkhead 110 and slid all the way downin channels 120. Base 140 is pivoted parallel to bulkhead 110, coveringhoop 130. If desired, the clamp 300 can be released, and the linkagearrangement 200 can be folded compactly against the side of the bulkhead110 opposite base 140, as shown in FIG. 6.
